I have an automatic 1994 Ford Tempo. I had worse problems this past weekend with it, so we OBD tested it and it said it was the MAF Sensor, so we changed it. Its running better, but a new problem arose after that!
It has no power, and its not the transmission. It takes forever to gain speed and get going, regardless the weather, time, temperature, and I always let it warm up good before leaving. It's really slow now and loses power if the road is flat or goes up hill. No matter how hard you push the gas pedal. And the gas pedal is fine too, so its not that either!
We're stumped and need help, so PLEASE help a working school girl out!!

Check the ignition module. Take it to any NAPA store and they will test it for free.

What was the original problem before you changed the MAF sensor? Looks like you may have a blocked exhaust and/or TPS sensor or even a weak fuel pump.

We checked everything electrical possible. Then my boyfriend gave us the idea of a catalytic converter.. So we took it in to the shop thinking that was really the problem. He checked all over it as well, then he saw that someone had loosened my distributor and the timing had to be reset on it. It had to be the guys at Wal-Mart cuz they changed my oil last, and its right beside the filter. Thank you all though! I'll let ya know what my next problem is when it happens, or what new car I get for graduation! ;)

Stupid Walmart oil change people! I quit having my oil changed at Walmart when they bent the clips on my hood pins of my 69 F100.

i just change my own oil, that way only one person is responsible.

The walmart person must've been VERY rough to loosen the distributor when reaching in to get the oil filter. It's a little in the way, but you have to be a total haystack to screw that one up.
